What does oilfield drilling fluids desander consist of
Oilfield drilling fluids desander is mainly composed of vibrating screen, bracket, electric control box, pressure gauge, manifold, cyclone and so on.
The working process of oilfield drilling fluids desander: the pump transports the sand-water mixture to the cyclone, and the fine sand concentrated by centrifugal classification is supplied to the vibrating screen through the grit chamber. After returning to the cleaning tank after the return box, when the liquid level of the cleaning tank is too high, it will be discharged through the discharge port. The weight concentration of the recovered material from the linear vibrating screen is 70%-85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar attempt, adjusting the overflow water volume, and replacing the sand outlet. So as to complete the three functions of cleaning, dehydration and classification.
The cyclone of oilfield drilling fluids desander is divided into two materials: one is high wear-resistant polyurethane material, and the other is high-chromium cast iron material. The advantages are economical and affordable, high temperature resistance, and the disadvantages are that it is not wear-resistant and has a short service life. Generally, it needs to be replaced once every 2000 hours; polyurethane The material is composed of three parts: volute, cone, and cone. Its advantage is wear resistance, the service life can be as long as 4200 hours, and the swirl effect is relatively good, but it is not resistant to high temperature.
